IOU TOKEN

The aim of IOU ecosystem is to give people proved fiat-free mutual settlements by issuing personal IOU tokens on Ethereum.

​

1. Alice, the artist,  wants to get service from Bob, the barber but she has no money right now :(. She can issue ERC20 compatible IOU token  and fill this:

   1. name of the token (Alice Artist 2020)

   2. symbol of the token (AA01)

   3. description of service (Artist: logos, infographic, cartoons)

   4. location (New York)

   5. social profile in LinkedIn (or Facebook or  smth else)

   6. units (dollars, euros, hours, pictures…)

2. Alice negotiated the sum of her AA01 tokens,  transfers this to Bob, and get the beautiful hairstyle. And this deal fixes in the blockchain forever.

3. Two-month later Bob asked her later for a cartoon about his hairdressing salon.

4. After Alice made her job, Bob burns a part of  Alice’s IOU tokens and puts feedback, adding a rating of results.

5. Later he pays with Alice’s AA01 tokens to Peter, the webmaster, who supports Bob’s salon website. Peter looks for a fresh infographic for another project.

6. Peter doesn’t know Alice personally and he wants to check Alice’s reputation. He gets the history of Alice’s deals and looks feedbacks and rates, given to Alice. From another user s of IOU tokens, number of transactions and supply amount.

7. If he decides that all ok, he approve the deal in Alice's IOU tokens.

8. After Piter receives results, hi burned tokens and gives his feedback too.
